The purpose of the study was to examine the concurrent and construct validity of a new perceptual scale to control the exercise intensity using elastic bands (Resistance Intensity Scale for Exercise; RISE) in the elderly. Twenty-six participants underwent two sessions consisting of 4 exercises. The participants performed three sets of 15 repetitions per exercise of either low, medium, or high intensity. The criterion variables were heart rate and applied force (mean and peak). Following the final repetition of each set, active muscle (AM) and overall body (OB) ratings of perceived exertion (RPE) were collected from RISE and the OMNI-Resistance Exercise Scale of perceived exertion with elastic bands (OMNI-RES EB). Construct validity was established by correlating the perceptual score obtained from both scales, RISE and OMNI-RES EB. Significant ( ≤ 0.05) and positive linear relationships between both scales were found (RPE-AM = 0.90; RPE-OB = 0.77). Significant differences in heart rate, applied force, and RISE scores were observed between the sets of the three intensities. For all 4 analyzed exercises, high-intensity sets elicited higher heart rate, applied force, and perceptual scores compared with the medium- and low-intensity sets. Furthermore, the medium-intensity sets produced higher perceptual, physiologic, and performance responses than the low-intensity sets. Intersession reliability was 0.88 for heart rate, 0.94 and 0.95 for applied force, 0.88 for the RPE-AM, and 0.80 for the RPE-OB. : The RISE scale can be considered a valid method for assessing the perceived exertion during resistance exercises performed with elastic bands in the elderly.
本研究旨在检验一种新的使用弹性带控制运动强度的感知量表（运动弹性带阻力强度量表；RISE）在老年人中的同时效和结构效度。26 名参与者进行了两次测试，每次测试包括 4 项运动。参与者以低、中、高强度完成每项运动的 3 组 15 次重复。因变量为心率和应用力（均值和峰值）。每组最后一次重复后，从 RISE 和弹性带 OMNI-阻力运动量表感知用力（OMNI-RES EB）中收集主动肌（AM）和全身（OB）感知用力（RPE）的评分。通过对两种量表（RISE 和 OMNI-RES EB）获得的感知得分进行相关性分析，来建立结构效度。两种量表之间存在显著（≤0.05）和正线性关系（RPE-AM = 0.90；RPE-OB = 0.77）。在三种强度的三组运动中，心率、应用力和 RISE 评分存在显著差异。对于所有 4 项分析运动，高强度组的心率、应用力和感知评分均高于中强度和低强度组。此外，中强度组产生的感知、生理和表现反应均高于低强度组。在所有分析的 4 项运动中，心率的组内信度为 0.88，应用力的组内信度为 0.94 和 0.95，RPE-AM 的组内信度为 0.88，RPE-OB 的组内信度为 0.80。结论：RISE 量表可被视为评估老年人使用弹性带进行抗阻运动时感知用力的有效方法。
